C'lk MICIIAKI, l(;STKK delivered his presi- 

 '■-' dcniial address before the British ;\)isociiUion ul 

 Dover on Wednesday, I3lh September. He may Ik- 

 said to have given the most p^)|)ulai addrcvs, yet by 

 no means the leiist valuable of all the long series. 

 His opporlunilles were great, as the close of the 

 nineteenth century lenl a splendid text. Sir Michael 

 availed himself of it to the utmost, and gave an 

 admirable summary of the scientific work done since 

 1799. When sve look aromul and think what science 

 has accomplished since that date for the comfort, nay, 

 the necessities, of nunkind, tlie_ lives lived by our 

 ancestors no more than a hinidred years ago seem to 

 us wonderful in their incompleteness. 



In opening his retrospect, ihe President reminded 

 us of what was not, in 1799. How men in Dover, 

 and elsewhere, groped tlieir ways at night by the help 

 of dim swinging lanterns, where now they are lit by 

 electric light, and travel by electric Iramcars. Then 

 even sunlight struggled into the houses of the |x)orer 

 clas.ses ihrovigh blurred glass. Now, the necessity of 

 brightness and light, whether by day or by night, is 

 recognised as absolute for vigour and health. Now, 

 everyone has opportunity to travel cheaply and 

 rapidly by the aid of steam power ; and to be kept 

 informed at an' hour's notice of the welfare, or 

 busine.ss progress at home, .\gain, he reminded us 

 that but a generation before, 1799, did Priestley 

 discover there was so important a gas as oxygen : 

 while even in 1799 the fact was understood by but few 

 of the better educated. That same year saw the birth 

 of a knowledge of electricity which afterwards, in its 

 infancy progressed so slowly. 



So on, did .Sir Michael carry his brilliant sunniiary 

 of the scientific work of the century. Touching im 

 every department, each in turn showed a dazzling 

 story of know ledge « rung from darkness, and applied 

 to the uses of mankind ; indeed, also to the relief of 

 sufTering of his fellow animals in their domestication, 

 all have benefited. 



What is the promise for the future? Compared 

 with that done in this century what ni.ay we expect in 

 the next 'i The earlier part of this was spent in 

 stumbling with obstacles that are now past, prejudices 

 that are overcome, and the opposition of dominant 

 ignorance, l-'or the future, science will rather have 

 to put the bre.ak of caution on the speed of the wheels 

 of public impatience for more and more knowledge. 

 No longer does commerce siteer at science, but refers 

 to its importance with many wise saws and much 

 respect. The young are no longer warned about 

 wasting time on scientific investigations, for is not 

 .systematic science taught in our schools day by day, 

 the very rudiments of which, in 1799, would have 

 been received with jeers ?
